Many people in Evergreen Park, Illinois who find their way to drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Actually, as many as 1/3 of those who suffer with mental health issues in Evergreen Park, Illinois also take part in substance abuse at some time in their lives. These dual diagnosis clients frequently turn to alcohol or drugs to self medicate in an attempt to alleviate the symptoms of an underlying psychiatric disorder. Some addicted individuals aren't even diagnosed with a disorder, and only when they make it to a drug rehab program is this sort of psychological condition discovered. This in itself can help resolve addiction issues and put the person in a position to get rehabilitation for both disorders so that they have a strong chance of remaining clean and sober and psychologically stable in the future.
